CHAPTER VIII
ARTIFICIAL LIMBS FOR AMPUTATION THROUGH THE ARM
In this chapter we shall deal only with amputation of the arm below the upper third, i.e. with cases in which the stump is long enough to transmit movements to the artificial limb. Amputation through the deltoid muscle must be considered in association with disarticulation of the shoulder.
